i figured the springs would have to be changed and i knew about the rods too, but i heard it doesnt have to be changed since its not really a problem... but i forgot to mention the springs! lol but i have a question if put this comp cam for the ls6 these are the specs Intake Exhaust

Gross Valve Lift .605 .613 (Lob Lift .3560 / .3610)

Duration @0.050 238 246

Duration @0.006 287 295

Lobe Separation 114.0



do i need to do any else? i know its not the stock specs , so do i have to get or do something else to insure i dont mess anything up once i put this in?
